cost = (reference value/bandwidth)×10, and the maximum calculated cost is
16777214.
z When the cost style is narrow, narrow-compatible, or compatible, if the
interface is a loopback interface, the cost value is 0; otherwise, the cost value is
automatically calculated as follows: if the interface bandwidth is in the range of 1 M
to 10 M, the interface cost is 60; if the interface bandwidth is in the range of 11 M to
100 M, the interface cost is 50; if the interface bandwidth is in the range of 101 M to
155 M, the interface cost is 40; if the interface bandwidth is in the range of 156 M to
622 M, the interface cost is 30; if the interface bandwidth is in the range of 623 M to
2500 M, the interface cost is 20, and the default interface cost of 10 is used for any
other bandwidths.

Parameters
value: Specifies the global link cost value. The value range varies with cost types.
z For types narrow, narrow-compatible and compatible: The cost value ranges
from 0 to 63.
z For types wide and wide-compatible: The cost value ranges from 0 to 16777215.
level-1: Applies the link cost to Level-1.
level-2: Applies the link cost to Level-2.
Description
Use the circuit-cost command to set a global link cost.
Use the undo circuit-cost command to restore the default.
By default, the global link cost is not configured.
